The influence of infill walls on seismic behavior of a historical building in Shanghai

Seismic assessment and seismic strengthening are the key issues need to be figured out during the process of protection and reusing of historical buildings. In this thesis the seismic behaviors of the hinged steel structure, a typical structure of historical buildings, i.e. hinged steel frames in Shanghai, China, were studied based on experimental investigations and theoretic analysis. How the non-structural members worked with the steel frames was analyzed thoroughly. Firstly, two 1/4 scale hinged steel frames were constructed based on the structural system of Bund 18, a historical building in Shanghai: M1 model without infill walls, M2 model with infill walls, and tested under the horizontal cyclic loads to investigate their seismic behavior. The Shaking Table Test and its results indicated that the seismic behavior of the hinged steel frames could be improved significantly with the help of non-structural members, i.e., surrounding elements outside the hinged steel frames and infilled walls. To specify, the columns are covered with bricks, they consist of I shape formed steel sections and steel plates, which are clenched together. The steel beams are connected to the steel column by steel angle, thus the structure should be considered as a hinged frame. And the infilled wall acted as a compression diagonal strut to withstand the horizontal load, therefore, the seismic capacity and stiffness of the hinged steel frames with infilled walls could be estimated by using the equivalent compression diagonal strut model. A SAP model has been constructed with the objective to perform a dynamic nonlinear analysis. The obtained results were compared with the results obtained from Shaking Table Test. The Test Results have validated that the influence of infill walls on seismic behavior can be estimated by using the equivalent diagonal strut model.

The Divine Eye in Ancient Egypt and in the Midrash Interpretation of Formative Judaism.

This paper studies the “eye” as a religious phenomenon from the multiple traditions of ancient Egypt compared with rabbinic Judaism in late antiquity using a semiotic approach based upon the theories of Umberto Eco. This method was chosen because the eye is a graphic as well as a linguistic sign which both express religious concepts. Generally, the eye represented an all-seeing and omnipresent divinity. In other words, the god was reduced to an eye, whereby the form of the symbol suggests a meaning to the viewer or religious practitioner. In this manner the eye represented the whole body of a deity in Egyptian and the power of a discerning God in rabbinic texts. By focusing upon the semantic aspect of the eye metaphor in both Egyptian and rabbinic texts two religious traditions of the visually perceivable are analyzed from a semiotic perspective.

Guidelines for the use and interpretation of assays for monitoring autophagy

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

The Pressures of History: Shakespearean Performance and Interpretation

Interpretations of Shakespeare’s characters have been subject to the pressures of history, exhibiting a progression of performance styles in accordance with changes in ideas and concerns over time. Shakespeare’s complex portrayals of women leave room for cultural influences of a time period to greatly influence interpretations because of the ambiguous nature of some of his major female characters. Lady Macbeth and Much Ado About Nothing’s Beatrice both overstep and challenge gender boundaries, and the combination of their defiant natures and textual ambiguities have made these characters highly controversial over the past four centuries.Various cultures over time have imposed specific readings of the characters that serve to reinforce the male-dominated expectations of a given society. The examination of variations in performance styles and interpretations of these two extremely canonical characters revealinsights into gender ideologies that existed during various time periods throughout history. The combination of this analysis with an exploration of the effects of the more recent applications offeminism and film, which have both helped to reshape the cultural images of both Lady Macbeth and Beatrice, will aide in an observation of the status of gender relations in our contemporary society. The current trend of interpretations of these characters could also provide predictions about future gender relations in our culture.
